Roy came to the airport in the 1940's after WWII. He was employed as a flight instructor to the first airport Marshfield Airport Manager Roy Kinland. Roy Shwery purchased the business from Roy Kinland and continued on with flight training. Roy and his wife Lois were one of the first aviation businesses to start a commuter airline. MidState Airlines was created in the 1950's and served many cities in Wisconsin, Minnesota, Michgan and Illinois. The first aircraft Roy used to start his airlines was a Beech 18. A replica of this aircraft can be seen today proudly at the entrance of the airport for all to see. (Pictured Right). This replica sits atop the airport sign letting all who pass by know where the airport is. The replica has the N-number of Roy's first Beech 18 as well as the paint scheme used on the airplane.

Roy and his wife Lois served as airport managers until 1978. Most everything on the airport today can be attributed to the work that Roy and Lois did for Marshfield.

In the early 2000's the airport received a name change to reflect all that Roy had done for Marshfield.
